nected : akenes narrow and elongated, minutely and all sparsely hairy, even those 

 of the ray, the latter salieutly 1 - 2-nerved ou each face ; outer oncis of the disk 

 apparently fertile : pappus of almost setiform plumose unequal chalfy scales, the 

 longer ones little shorter than the corolla. — Anisocar2ms Bolauderi, Gray, Proc. 

 Am. Acad. vii. 360. 



Woods of the Sierra Nevada : in tlie Mariposa Sequoia grove, and at Conner Lake, Bolandcr. 

 Heads half an inch high : rays 3 lines long. Akenes 3 lines long ; those of the ray lanceolate- 

 falcate, sometimes bearing the rudiments of a pappus like that of the disk, but much reduced ! 



* * Disk-floivers loholbj destitute of pappus, either all or only the central ones sterile: 

 leaves almost all alternate. {^Aladaria, DC.) 



3. M. elegans, Don. Pubescent, and more or less hirsute or even hispid, as 

 well as glandidar, one or two feet high, or in depauperate slender forms only a span 

 or so in height : heads loosely corymbose or paniculate : scales of the involucre with 

 slender linear tips : rays (10 to 15 in the larger, 5 to 9 in depauperate forms) elon- 

 gated, acutely 3-lobed at apex, yellow throughout, or often with a brown-red spot at 

 base : disk-flowers all sterile, on a strongly convex hirsute-fimbrillate receptacle : 

 fertile akenes obliquely obovate, the areola at the thick truncate summit depressed. 

 — Madaria elerjans & M. coryinhosa, DC, &c. 31. racemosa, Kutt., one of the 

 slender forms. 



Hills and plains, througliout California and in Oregon and Nevada. Very variable in size, 

 pubescence, glandulosity, and number of tiowers in the head ; but all apparently of one species. 

 The larger forms are handsome in cultivation. 



4. M. radiata, Kellogg. Viscid-pubescent and glandular, 2 or 3 feet high : 

 heads pretty large : scales of the involucre with short tips : rays 9 to 20, golden- 

 yellow, broadly "oblong or somewhat cuneiform, obtusely 3-toothed : disk-flowers 

 also fertde except the central ones, on a nearly flat and glabrous receptacle ; their 

 akenes somewhat clavate and 4-angular, straightish, with depressed areola at 

 summit ; ray-akenes narrowly obovate-falcate, fiat, tipped with a very short beak 

 which is reflexed upon the summit of the akene. — Proc. Calif Acad. iv. 190. 



Near the mouth of the San Joaciuin River, Bolandcr. Head broad : ligules half an inch long, 

 abrupt at base. 



§ 2. Bays short and more or less inconsjncuous, 12 to \,or rarely ivanting altogether: 

 disk-flowers numerous or feiv, all fertile, destitide of pa2)pus, and with corolla- 

 tuhepuhescent : recep)tade flat and smooth. — Eumadia. 



5. M. sativa, Molma. Viscid-hirsute and glandular, heavy-scented, one to 

 three feet high : heads racemose or paniculate, often glomerate : ray-flowers 5 to 

 12 : disk-flowers about the same number : akenes obovate-oblong and shghtly 

 curved, or those of the ray obovate-lunate, those of the disk commonly (and of the 

 ray sometimes) 1 -nerved down the sides. — The following forms pass freely into 

 each other. 



Var. congesta, Torr. & Gray : a large and very glandular, common form : the 

 many-flowpred heads sessile in crowded clusters : akenes (as in the ChiHau plant) 

 rather narrow and mostly angled by the prominent nerve on 1;he two sides. — M. 

 capitata, Nutt., not "congesta" as printed in Torr. & Gray, Fl. ii. 404. 



Var. racemosa, Gray : a smaller and more slender form : commonly fewer-flow- 

 ered heads rather loosely racemose or i)anicled : akenes usual with less prominent or 

 obsolete lateral nerves. — .1/. racemosa, Torr. & Gray, 1. c. . Madorella racemosa, Isutt. 



Var. diSSitiflora, Gray : like the preceding or more depauperate, with scattered 

 or panicled smaller and mostlv fewer-flowered heads, often only 5 rays an.l as tew 

 disk-flowers : akenes inclined to short-obovate (H to 2 lines long), and with eitlier 

 flat and nerveless or else 1-nerved sides.— J/, dissitlflora, Torr. & Gray. Madorella 

 dissitifl.ora, Nutt.
